Toxic shock syndrome in 8 children

OBJECTIVE: Evaluation of patients with toxic shock syndrome (TSS) in a paediatric hospital. DESIGN: Retrospective analysis. SETTING: Paediatric Intensive Care Unit, University Hospital, Rotterdam, the Netherlands. METHOD: Analysis of the medical records on 155 patients admitted between January 1982 and January 1992 suffering from shock, 8 of whom had TSS. RESULTS: Five out of 8 TSS patients were under 5 years of age. All the patients needed mechanical ventilation. All patients survived. In 7 patients a probably causative focus of infection was found. The cultures of 6 patients showed growth of Staphylococcus aureus, those of 2 patients showed Lancefield group A beta-haemolytic streptococci (bacterial culture in one, increased antibody titer in the other). Systematic phage typing was not performed. CONCLUSION: Although TSS is a relatively rare disease in young children, it is a potentially lethal one, early recognition of which is very important.     

Toxic shock-like syndrome after acupuncturation

A 80-year-olkd male was admitted to our hospital because of severe pain and swelling on his left lower leg on January 23, 1996. He had received an acupuncture to both legs because of intermittent claudication once a week from July, 1995 to January 18, 1996. On the next day of the last acupuncture, pain and swelling on his left leg appeared. On admission, his left leg showed diffuse swelling and redness with blisters. We diagnosed this patient as toxic shock-like syndrome (TSLS), based on the rapid exacerbation of the skin changes, necrotizing superficial fasciitis, multiple organ failure with shock, and the detection of group A streptococcus from culture samples obtained from both skin blister and necrotic fascia. He recovered from the disease by amputation of the involved leg and antibiotic therapy. Acupuncture could have been the cause of streptococcal infection.     

Toxic shock syndrome presenting as postoperative diarrhea in a postmenopausal woman

Three days after laminectomy, toxic shock syndrome (TSS) presented as acute diarrhea, rash, and fever in a 62-year-old postmenopausal woman. Forty-eight hours later, the full syndrome of TSS developed. Exploration of a benign-appearing wound revealed an occult Staphylococcus aureus infection. This report and literature review underscore the need to consider TSS in the differential diagnosis of acute diarrhea regardless of age, sex, race, and menstrual status, particularly when there has been recent soft tissue infection, injury, or surgery of any type.     

Toxic shock syndrome complicating orthopaedic manipulation of bone. A report of two cases

We studied prospectively 81 consecutive patients undergoing hip surgery using the Hardinge (1982) approach. The abductor muscles of the hip in these patients were assessed electrophysiologically and clinically by the modified Trendelenburg test. Power was measured using a force plate. We performed assessment at two weeks, and at three and nine months after operation. At two weeks we found that 19 patients (23%) showed evidence of damage to the superior gluteal nerve. By three months, five of these had recovered. The nine patients with complete denervation at three months showed no signs of recovery when reassessed at nine months. Persistent damage to the nerve was associated with a positive Trendelenburg test.     

Toxic shock syndrome: case report of a postpartum female and a literature review

1. 1alpha,25-dihydroxyvitamin3 (VD) is a nuclear hormone that has important cell regulatory functions but also a strong calcemic effect. EB1089 is a potent antiproliferative VD analogue, which has a modified side chain resulting in increased metabolic stability and a selective functional profile. Since EB1089 is considered for potential systemic application, it will be investigated to what extent its recently identified metabolites (hydroxylated at positions C26 and C26a) contribute to biological profile of the VD analogue. 2. Limited protease digestion analysis demonstrated that EB1089 is able to stabilize the high affinity ligand binding conformation of the VDR, starting at concentrations of 0.1 nM and affecting up to 80% of all receptor molecules. The metabolites EB1445 and EB1470 showed to be 100 fold less potent than EB1089, whereas the remaining three metabolites (EB1435, EB1436 and EB1446) showed a clearly reduced ability to stabilize the high affinity ligand binding conformation. Interestingly, at pharmacological concentrations all EB1089 metabolites stabilized a second, apparently lower affinity conformation to a much higher extent than EB1089. 3. In reporter gene assays all metabolites showed lower potency than EB1089. Moreover, the preference of EB1089 for activation of VDR binding to sites formed by inverted palindromic arrangements spaced by nine nucleotide (IP9-type VD response elements) appeared to be reduced (with EB1445 and EB1470) or completely lost (with EB1435, EB1436 and EB1446). The ranking of EB1089 and its metabolites that was obtained by limited protease digestion and reporter gene assays was confirmed by an analysis of their antiproliferative effect in breast cancer cells. . The potency and selectivity of the EB1089 metabolites in mediating gene regulatory effects was found to be drastically reduced in comparison to the parent compound suggesting that the contribution of the metabolites to the biological effect of EB1089 is minor. However, the compounds showed to be interesting tools for understanding the selective biological profile of EB1089.     

Delayed toxic shock syndrome after functional endonasal sinus surgery

Esophagopericardial fistula is a rare entity, usually associated with benign esophageal disorders. Clinically they present as an acute illness associated with characteristic clinical findings and have an extremely high mortality rate. A case of a chronic esophagopericardial fistula is presented in an individual who remained asymptomatic and presented as a sudden unexpected death secondary to cardiac tamponade from refluxed gastric contents.     

"Toxic sock" syndrome

For several months, a 17-year-old male athlete noticed that his feet had an itchy, burning sensation at the heels and toes. His foot odor had become so malodorous (somewhat akin to rotting fish) that he would not remove his shoes except immediately before washing his feet. Washing made the odor somewhat milder, but only for a short time. The patient had tried an over-the-counter "athlete's foot" powder without results. He had no other health problems and was not taking any medication. The accompanying figure shows the toes of his right foot.     

Toxic epidermal necrolysis after treatment with lamotrigine

A case of toxic epidermal necrolysis following treatment with lamotrigine is presented. A 20 year old male suffering from epilepsy was treated with lamotrigine in addition to valproic acid. After three weeks he developed cutaneous manifestations of Steven-Johnson's syndrome followed by toxic epidermal necrolysis, mucosal lesions and liver symptoms. He was treated with systemic corticosteroids, antibiotics and intravenous fluid, and recovered after a few weeks.     

Risk factors in dengue shock syndrome

Despite a growing body of evidence predominantly, but not exclusively, from Thailand suggesting that the risk of developing dengue shock syndrome (DSS) is greatest following an anamnestic dengue infection, particularly if the most recent infection was with dengue 2 virus, there continues to be debate about the justification for these claims. This report describes a five-year, prospective study in two townships (suburbs) in Yangon (Rangoon) Myanmar (Burma) in which attempts were made to confirm the data from an earlier prospective study in Thailand and to address some of the criticism of earlier studies. This investigation found the incidence of anamnestic dengue infections in DSS patients to be significantly higher than in the community from which they were drawn and a significantly higher risk of developing DSS following an anamnestic infection (particularly with dengue 2 virus) than following a primary infection with any serotype.     

Streptococcal toxic shock syndrome complicating preseptal cellulitis

PURPOSE: To document the static nature of crystalline deposits in talc retinopathy. METHOD: Case report. RESULTS: A 38-year-old woman with a remote history of intravenous drug abuse showed the incidental finding of fine, irregularly shaped refractile deposits in the retinal microvasculature. At 2-year follow-up, fundus findings were identical to the initial manifestation with respect to the distribution and position of crystalline deposits in each fundus. CONCLUSION: This case documents the static nature of crystalline deposits in talc retinopathy.     

Toxic and hemolytic properties of serum in the massive transfusion syndrome

Toxic and hemolytic properties of the sera of dogs which received massive homologus blood transfusions were studied in experiments on 20 dogs and 432 mice. The toxicity of the recipient's sera was evaluated in vivo on mice with blocked reticulo-endothelial system and by the method of hemocultures. Red cells labeled with radioactive chromium were used to study the hemolytic activity. Investigations carried out demonstrated the acute blood loss wilth the subsequent massive transfusion of the homologous blood to result in the production in the recipient's serum of toxigenic products. These toxigenic properties were determined by two biotesting methods. The maximal toxigenic action was noted in 2 hours and in the course of the 1st day after the substitution. No toxic effect of the sera was found on the 17th day. A parallel study of hemolytic properties of the sera revealed a marked increase of its activity; it was the greatest during the first 24 hours. In three days the hemolytic properties of the serum were no different from the initial one.     

Presumed anaphylactic shock after infusion of Lipofundin

A case of anaphylactic shock in a 45 year old man with Hodgkin's disease following Lipofundin infusion is described. Lipofundin is a soybean oil based preparation for parenteral nutrition. Allergic reactions to lipid infusions are only very seldom described, but it is important to be aware of the possibility of anaphylaxis, as this case-story demonstrates. Allergy to soy-proteins is well-known, whereas soybean oil is not allergenic in soybean-sensitive individuals. Soy-protein, in small quantities, can be detected in soy-oil. A possible connection between the patient's reaction and soy-allergy is discussed.     

Prolonged immunodepression after trauma and hemorrhagic shock

OBJECTIVE: To define and discuss the cytologic findings in six cases of nodular pseudoangiomatous stromal hyperplasia (PASH) of the breast. STUDY DESIGN: Retrospective evaluation of the medical records, cytologic and histologic material from six patients with palpable mammary PASH. Cases in which PASH was associated with other predominant mammary lesions were not included in the study. RESULTS: A total of six patients with histologically proven PASH underwent aspiration in nine occasions (three patients studied twice). Clinically, five patients were diagnosed as having fibroadenoma or another benign lesion, and in one patient carcinoma was suspected. In two patients, mammography disclosed rapid growth of the lesion. Seven aspirations, performed on five patients, were diagnosed as fibroadenoma (n = 5) or fibroadenomatous lesion (n = 2). An eighth aspiration was cystic and reported as fibrocystic disease. The last case was erroneously diagnosed as suspicious for carcinoma. Even after revision, the cytologic similarities of PASH with fibroadenoma were remarkable. Most smears were less cellular than those of conventional fibroadenomas. Epithelial clusters showed variable size, with a predominance of medium to small groups. Stromal elements were minimal or absent. Background cellularity was composed of round to oval naked nuclei and others with spindle shapes. Occasional epithelial clusters showed cellular dissociation and slight atypia. CONCLUSION: Due to the absence of specific cytologic features and similarities to fibroadenoma, a precise diagnosis of PASH cannot be made on cytologic material. However, the majority of cases can be diagnosed correctly as benign, allowing appropiate treatment.     

Phaeochromocytoma with adult respiratory distress syndrome mimicking septicaemic shock

Phaeochromocytomas are rare tumours that most commonly present with chronic sustained hypertension and hypertensive paroxysms or crises. We report a 49-year-old woman with unsuspected phaeochromocytoma who presented with sudden onset of profound hypotension and adult respiratory distress syndrome unresponsive to fluid and inotropic support. This case illustrates the diversity of presentations of phaeochromocytoma, depending on the type and amount of catecholamines secreted.     

Septic shock in patients with the acquired immunodeficiency syndrome

OBJECTIVE: To evaluate the prognosis of patients with septic shock admitted to an intensive care unit (ICU), according to their HIV serostatus. DESIGN: Retrospective study. SETTING: Medical ICU of a university hospital. PATIENTS: 76 patients with septic shock admitted to the same ICU, of whom 28 were HIV positive and 48 were HIV negative. MEASUREMENTS AND RESULTS: Severity scores, number and type of organ failures, and survival rates were assessed in the two groups of patients. Glasgow Coma Scale and general severity scores [Acute Physiology and Chronic Health Evaluation II and Simplified Acute Physiology Score (SAPS)] were significantly worse in HIV-infected patients. The total number of organ failures was also higher in the HIV-positive group: 3.7 +/- 0.2 vs 3.1 +/- 0.2 in the HIV-negative group (p < 0.001). On day 28, 21 (46%) HIV-negative patients were dead compared to 26 (93%) patients in the HIV-positive group (p < 0.001). In the multivariate analysis, HIV infection was an independent risk factor for mortality, as were the SAPS score, use of mechanical ventilation, and the McCabe score. CONCLUSIONS: This study reports a considerable excess mortality in HIV-infected patients with septic shock. Although severity of illness was clearly much more pronounced in HIV-positive patients, retroviral infection was independently associated with death. Improving survival in HIV-positive patients with septic shock may require earlier diagnosis and treatment of the causative infection.     

Acoustic mechanisms: canal wall-up versus canal wall-down mastoidectomy

The contribution of the middle ear air spaces to sound transmission through the middle ear in canal wall-up and canal wall-down mastoidectomy was studied in human temporal bones by measurements of middle ear input impedance and sound pressure difference across the tympanic membrane for the frequency range 50 Hz to 5 kHz. These measurements indicate that, relative to canal wall-up procedures, canal wall-down mastoidectomy results in a 1 to 5 dB decrease in middle ear sound transmission below 1 kHz, a 0 to 10 dB increase between 1 and 3 kHz, and no change above 3 kHz. These results are consistent with those reported by Gyo et al. (Arch Otolaryngol Head Neck Surg 1986;112:1262-8), in which umbo displacement was used as a measure of sound transmission. A model analysis suggests that the reduction in sound transmission below 1 kHz can be explained by the smaller middle ear air space volume associated with the canal wall-down procedure. We conclude that as long as the middle ear air space is aerated and has a volume greater than 0.7 ml, canal wall-down mastoidectomy should generally cause less than 10 dB changes in middle ear sound transmission relative to the canal wall-up procedure.     

Magnesium deficiency and cardiogenic shock after cardiopulmonary bypass

Magnesium is an important cation that has a key role in cellular processes of energy transfer and utilization involving adenosine triphosphate, and influences cell membrane functions. Its antiarrhythmic properties are well-known and it is widely recognized as an adjunct for the treatment of arrhythmias after myocardial infarction and cardiopulmonary bypass. Magnesium may influence hemodynamic performance through its effects on vascular tone, modulation of intracellular calcium, regulation of catecholamine activity, and its essential role in adenosine triphosphate metabolism. The potential for magnesium deficiency to affect cardiovascular performance may be especially relevant in ischemic states. We report a case of cardiogenic shock developing after cardiopulmonary bypass that was initially unresponsive to therapeutic intervention, but that resolved promptly after magnesium administration. The potential role of magnesium in enhancing hemodynamic performance is discussed, with a review of its cellular metabolic properties and activities.
